I remembered what Thoreau had written in his journal about thinking nothing of walking eight miles to greet a tree.

Humans are animals and like all animals we leave tracks as we walk: signs of passage made in snow, sand, mud, grass, dew, earth or moss.... We easily forget that we are track-markers, through, because most of our journeys now occur on asphalt and concrete--and these are substances not easily impressed.

All travelers to wild places will have felt some version of this, a brief blazing perception of the world's disinterest. In small measures it exhilarates. But in full form it annihilates.

Anyone who lives in a city will know the feeling of having been there too long. The gorge-vision that the streets imprint on us, the sense of blockage, the longing for surfaces other than glass, brick, concrete and tarmac....I have lived in Cambridge on and off for a decade, and I imagine I will continue to do so for years to come. And for as long as I stay here, I know I will have to also get to the wild places.

Woods and forests have been essentialt to the imagination of these islands, and of countries throughout the world, for centuries. It is for this reason that when woods are felled, when they are suppressed by tarmac and concrete and asphalt, it is not only unique species and habitats that disappear, but also unique memories, unique forms of thought.

We are fallen mostly into pieces but the wild returns us to ourselves
